Professor, Cognitive Science
Dr. Brennan plans to recruit a new graduate student for the 2020-2021 academic year, pending funding availability. 

Research Interests:

I am a cognitive scientist who studies the psychology of language use--in particular, interactive spoken dialogue. Some of my current studies use eye-tracking, either as a measure of language processing or as a mode of communication.  I also study the human use of technology, especially speech and language interfaces to computers. Previously, I developed a computational model of caricature.

Current Research:

The psycholinguistics of spoken dialogue; eye gaze as a nonverbal signal and as an on-line measure of language processing; coordination of speaking and listening in conversation; production and comprehension of referring expressions; joint attention  and coordination; speech disfluencies;  audience design; writing for a reader's comprehension; spoken dialogue  interfaces to computers; human-AI interaction; multimodal  communication; communication between native and non-native speakers of English
